I've used dry heat on green hickory, mulberry, juniper, and elm. The best results were with the juniper, the worst with the hickory. By worst I mean the compression side of the bend showed deep wrinkles.....much more drastic than crysals. The elm and mulberry bent with less compression failure but sometimes lifted splinters on the tension side. In general, steam works a lot better than dry heat on green wood. The bends are cleaner, easier to make, and last longer under heavy use, in my experience.
